Abstract
Description
Technical Field
[0001] This invention relates to the field of olfactory assessment technology, specifically to an intelligent olfactory assessment and self-diagnosis system. Background Technology
[0002] In existing technologies, the assessment of olfaction mostly relies on subjective judgment. This involves preparing liquids with different concentrations of odor and then identifying the liquids from low to high concentrations to determine if one's sense of smell is normal. However, this method is not only less accurate, but the measurement results can also be biased when the surrounding environment changes. Summary of the Invention
[0003] Therefore, the present invention provides an intelligent olfactory assessment and self-diagnosis system to solve the above-mentioned problems in the prior art.
[0004] To achieve the above objectives, the present invention provides the following technical solution:
[0005] According to a first aspect of the present invention, an intelligent olfactory assessment and self-diagnosis system includes a signal collector, an odor generator, and a data processor.
[0006] The signal acquisition device includes an electroencephalogram (EEG) acquisition module, a processing module, and a first connection module. The EEG acquisition module is used to contact the user's head and is installed at a designated position on the user's head. The EEG acquisition module can acquire the user's EEG data and transmit the acquired data to the processing module. When the processing module receives the information acquired by the EEG acquisition module, it can filter the received signal and transmit the filtered signal to the data processor through the first connection module.
[0007] The odor generator includes an odor generating module, a programmable control module, and a second connection module. The odor generating module generates a gas with a specified odor at a predetermined power. The programmable control module controls the power of the odor generating module, allowing it to emit gases of different concentrations at different power levels. The second connection module is connected to a data processor.
[0008] The data processor includes an interface module, a display module, and a judgment module. The first connection module and the second connection module are connected to the data processor through the interface module. The display module can receive brainwave signals and the power of the odor generation module, and draw the electrical signal spectrum of brainwaves.
[0009] Furthermore, the EEG acquisition module includes multiple acquisition units, each positioned at a different location on the head, to comprehensively acquire EEG data.
[0010] Furthermore, when drawing an electrical signal spectrum, the display module can correlate the electrical signal value of the brainwave with the power value of the odor generating module and display the two on the spectrum.
[0011] Furthermore, the display module is provided with a planar coordinate system. The horizontal axis of the planar coordinate system is the power value of the odor generating module, and the vertical axis of the planar coordinate system is the electrical signal value of the brain waves. When the sense of smell does not receive sufficient stimulation, the electrical signal value of the brain waves is 0, and at this time, the electrical signal value of the brain waves coincides with the horizontal axis of the coordinate system.
[0012] Furthermore, the data processor also includes a judgment module and an output module. The judgment module can evaluate the user's olfactory state based on the graph on the display module, and the judgment module can divide the evaluation results into multiple levels. The output module can output the evaluation results.
[0013] Furthermore, the judgment module is equipped with multiple different baselines, and different baselines correspond to different evaluation results. The baselines are set in a plane coordinate system and are parallel to the horizontal axis. Multiple baselines are distributed sequentially from bottom to top in the plane coordinate system.
[0014] Furthermore, the data processor also includes a control module, which can control the programmable module. When the power of the odor generating module exceeds a preset value or the electrical signal value of the brainwave exceeds the uppermost baseline, the control module can control the programmable module so that the power of the odor generating module can be reduced to zero.
[0015] The present invention has the following advantages:
[0016] When implementing the technical solution of this invention, the signal collector is installed on the user's head to collect the user's brain waves, while the odor generator can emit gases of different concentrations. When the user uses this system, the user's olfactory state is measured according to the different concentrations of gas, thereby determining whether the user's sense of smell is normal. The data processor can process the collected brain wave signals and display them, and in the process, it can also judge the user's olfactory state to achieve the purpose of self-diagnosis.
[0017] In this invention, the user's electroencephalogram (EEG) information is collected by a data acquisition module to determine whether the user's sense of smell has been stimulated. However, the data acquisition module may be affected by various factors (such as air temperature and humidity, and the contact between the module and the user's head). To eliminate these influences, a processing module is included. The collected EEG information is then transmitted to a data processor via a first connection module.
[0018] An odor-generating module produces a stimulating gas. When a user perceives this gas, their brainwaves change accordingly when their sense of smell is normal. A programmable control module regulates the power of the odor-generating module, allowing it to emit gases of varying concentrations. This allows the module to adjust the gas concentration if the user fails to recognize low concentrations. A second connection module transmits the power of the gas-generating module to a data processor. Since the power of the gas-generating module corresponds to the gas concentration, the data processor can acquire the gas concentration data.
[0019] The display module allows users to more intuitively understand their own olfactory state. Attached Figure Description
[0020] Figure 1 This is a schematic diagram of the structure of an intelligent olfactory assessment and self-diagnosis system provided in some embodiments of the present invention. Detailed Implementation
[0021] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1
[0023] like Figure 1 As shown in the first aspect embodiment of the present invention, an intelligent olfactory assessment and self-diagnosis system includes a signal collector, an odor generator, and a data processor. The signal collector is installed on the user's head to collect the user's brainwaves. The odor generator emits gases of different concentrations. When the user uses the system, the system measures the user's olfactory state based on the different gas concentrations, thereby determining whether the user's olfactory sense is normal. The data processor processes and displays the collected brainwave signals, and in the process, it can also determine the user's olfactory state to achieve the purpose of self-diagnosis.
[0024] The signal acquisition device includes an electroencephalogram (EEG) acquisition module, a processing module, and a first connection module. The EEG acquisition module is used to contact the user's head and is installed at a designated position on the user's head. The EEG acquisition module can acquire the user's EEG data and transmit the acquired data to the processing module. When the processing module receives the information acquired by the EEG acquisition module, it can filter the received signal and transmit the filtered signal to the data processor through the first connection module.
[0025] The odor generator includes an odor generating module, a programmable control module, and a second connection module. The odor generating module generates a gas with a specified odor at a predetermined power. The programmable control module controls the power of the odor generating module, allowing it to emit gases of different concentrations at different power levels. The second connection module is connected to a data processor.
[0026] The data processor includes an interface module and a display module. The first connection module and the second connection module are connected to the data processor through the interface module. The display module can receive brainwave signals and the power of the odor generation module, and draw the electrical signal spectrum of brainwaves.
[0027] The EEG acquisition module can collect weak electrical signals from the cerebral cortex, amplify, filter, and digitize the signals for display. The gas generated by the odor generation module can stimulate the human sense of smell. After stimulation, the electrical signals of the cerebral cortex will change, and the olfactory function will be judged based on the magnitude of the change.
[0028] In this invention, the user's electroencephalogram (EEG) information is collected by a data acquisition module to determine whether the user's sense of smell has been stimulated. However, the data acquisition module may be affected by various factors (such as air temperature and humidity, and the contact between the module and the user's head). To eliminate these influences, a processing module is included. The collected EEG information is then transmitted to a data processor via a first connection module.
[0029] An odor-generating module produces a stimulating gas. When a user perceives this gas, their brainwaves change accordingly when their sense of smell is normal. A programmable control module regulates the power of the odor-generating module, allowing it to emit gases of varying concentrations. This allows the module to adjust the gas concentration if the user fails to recognize low concentrations. A second connection module transmits the power of the gas-generating module to a data processor. Since the power of the gas-generating module corresponds to the gas concentration, the data processor can acquire the gas concentration data.
[0030] The display module allows users to more intuitively understand their own olfactory state.
[0031] The EEG acquisition module includes multiple acquisition units, each positioned at a different location on the head, to comprehensively acquire EEG data. By monitoring different locations on the user's head, more accurate EEG data can be obtained.
[0032] When drawing an electrical signal spectrum, the display module can correlate the electrical signal values of the brain waves with the power values of the odor generating module and display them on the spectrum.
[0033] The display module is equipped with a planar coordinate system. The horizontal axis of the planar coordinate system represents the power value of the odor generating module, and the vertical axis represents the electrical signal value of the electroencephalogram (EEG). When the sense of smell does not receive sufficient stimulation, the electrical signal value of the EEG is 0, and at this time, the electrical signal value of the EEG coincides with the horizontal axis of the coordinate system. This graphical representation (planar coordinate system) allows users to more intuitively understand their own olfactory state.
[0034] The data processor also includes a judgment module and an output module. The judgment module can evaluate the user's olfactory state based on the graph on the display module, and the judgment module can divide the evaluation results into multiple levels. The output module can output the evaluation results.
[0035] The judgment module has multiple different baselines, and different baselines correspond to different evaluation results. The baselines are set in a plane coordinate system and are parallel to the horizontal axis. Multiple baselines are distributed in the plane coordinate system from bottom to top.
[0036] The data processor also includes a control module, which can control the programmable module. When the power of the odor generating module exceeds a preset value or the electrical signal value of the brainwave exceeds the uppermost baseline, the control module can control the programmable module to reduce the power of the odor generating module to zero, thereby avoiding the problem of the power of the odor generating module continuously increasing and protecting it to a certain extent.
